dahdi_test

NAME
dahdi_test — Test if the DAHDI timer provides timely response

SYNOPSIS
dahdi_test [ -v ]

DESCRIPTION
dahdi_test dahdi_test runs a timing test in a loop and prints the
result of each loop. The test is as follows:

   It reads 8192 bytes from the DAHDI  timer  device  (/dev/dahdi/pseudo).
   This  should  take  exactly  8000 ms . It uses calls to gettimeofday(2)
   before and after that read to check that  indeed  exactly  8000ms  have
   passed.

   Values  of  100%  and  99.99%  Are normally considered a definite pass.
   Values of 99.98% and 99.97% are probably OK as well.

OPTIONS
-v
Be more verbose: print one line per test.

   -c count
          Run for count times instead of running forever.

FILES
/dev/dahdi/pseudo
The device file used to access the DAHDI timer.
